arogozhnikov opened a new issue #12761: Shape_array returns random numbers
URL: https://github.com/apache/incubator-mxnet/issues/12761
 
 
   ## Minimum reproducible example
   
   ```python
   import mxnet as mx
   x = mx.sym.Variable('x', shape=(2, 3, 4), dtype='float32')
   print(x, x.infer_shape(), x.infer_type())
   shape = x.shape_array()
   print(shape, shape.infer_shape(), shape.infer_type())
   
   x_computed = x.bind(mx.cpu(), args={x.name: mx.nd.zeros((2, 3, 4), dtype='float32')})
   print('x_computed', x_computed.outputs)
   
   # this last one is the only that looks absolutely wrong
   shape_computed = shape.bind(mx.cpu(), args={x.name: mx.nd.zeros((2, 3, 4), dtype='float32')})
   print('shape_computed', shape_computed.outputs)
   ```
   
   ## Output
   
   ```
   <Symbol x> ([(2, 3, 4)], [(2, 3, 4)], []) ([<class 'numpy.float32'>], [<class 'numpy.float32'>], [])
   <Symbol shape_array4> ([(2, 3, 4)], [(3,)], []) ([<class 'numpy.float32'>], [<class 'numpy.int64'>], [])
   
   x_computed [
   [[[0. 0. 0. 0.]
     [0. 0. 0. 0.]
     [0. 0. 0. 0.]]
   
    [[0. 0. 0. 0.]
     [0. 0. 0. 0.]
     [0. 0. 0. 0.]]]
   <NDArray 2x3x4 @cpu(0)>]
   
   shape_computed [
